UNITED STATES PATENT OFFICE.

OLE R. IIAUSKEY, OF LAKE PRESTON, SOUTH DAKOTA.

MERRY-GO-ROUND.

SPECIFICATION forming part of Letters Patent No. 616,923, dated January3, 1899. Application filed September 24,1897. Serial No. 652,887. (N0model.)

.T0 @ZZ whom, it may concern:

Be it known that I, OLE R. lIAUsKEY, a citizen of the UnitedStates,residing at Lake Preston, in the county of Kingsbury and State ofSouth Dakota, have invented certain new and useful Improvements inMerry-go-Rounds; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to makeand use thesame.

This invention relates to improvements in merry-go-rounds; and itconsists of certain novel constructions, combinations, and arrangementsof parts, all of which will be hereinafter more particularly set forthand claimed.

In the accompanying drawings, forming part of this specification, Figure1 represents a side elevation, partly broken away, of the apparatusembodying my invention. Fig. 2 represents a top plan view, partly brokenaway, of the same; and Fig. 3 represents an enlarged detail perspectiveview of the spring supporting-frame.

1 in the drawings represents the base; 2, the supporting-frame mountedthereon; 3, the main shaft; Ll, the power-wheel; 5, thesuspending-wheel, and G 6 the chair. Said base 1 comprises a centralportion or stopblock 7 and a plurality of radiating braces or arms 8 8,rigidly connected thereto. Said frame 2 comprises a plurality ofvertical standards 9, mounted upon the radiating arms 8 and connected attheir upper ends by crossarms 10, which latter are provided at the pointof intersection with an aperture 11, through which the shaft 8 looselypasses. The lower end of this shaft is preferably beveled, as at l2, andis mounted in a suitable recess 13, formed in the stop-block 7. Theupper portion of said shaft 8 is formed with a vertical groove adaptedto receive a stud or projection 15, mounted in the aperture 16 of thecentral solid portion 17 of the suspendingwheel. By this means saidcentral portion 17 rotates with the shaft 3, but may rise or fallindependently of the same. Coil-springs 18 .and 19 surround the shaft 3below and above the portion 17 and have their respective inner endsconnected to the latter. The

outer ends of said springs are made fast to suitable nuts or washers 2Oand 2l, fast upon said shaft 3.

It will be observed from the foregoing de scription that the centralportion 17 is held midway between the outer ends of the springs 1S and19 and is free to move either up or down against the tension of saidsprings. A plurality of radiating arms 22 are mounted on said centralportion 17 and are supported and braced in position by inclinedbrace-bars 23, connected at their outer ends to the outer ends of thebars 22 and at their inner ends to vertical standards 24, mounted uponthe central portion 17. The outer ends of said arms 22 are connected bya circular hoop or ring 25. A plurality of pendent yoke-frames 26 arearranged upon saidhoop 25 and are provided, respectively, upon oppositesides with spaced guide studs or pins 27, between 1 which supportingbars 2S are adapted to slide. The upper ends of each pair of these barsare connected by an apertured block 29, adapted to t about a guiding-rod30, which latter has its respective ends secured to the lower portion ofthe yoke 26 and the hoop 25. A coil-spring 31 surrounds said rod 8O andbears with its lower end upon the bottom of the yoke.' The block 29rests upon the upper end of said spring 31, so that any downwardmovement of the rods 28 will be against the tension of said spring 31.Said rods 2S are pivotally connected at their lower ends to the oppositesides of a block 32, which is fast upon the top of the pendent yoke 33,to the bottom of which is secured any desirable form of seat or basket.In order to prevent any abnormal lateral oscillation of the basket 6, Iconnect one side of the yoke 33 with one of the arms 22 by means of acoil-spring 35, which latter holds the basket normally in the samevertical plane with the hoop 25. Said shaft 8 is provided with asuitable power-wheel 34, fast thereon and adapted to be connected to anysuitable source of power. In the present instance I have shown cog-teeth37 on said wheel and provided a pinion 3S to mesh therewith, said pinionbeing driven by a crankshaft 30, suitably journaled on the frame 2. Ifso desired, said power-wheel 34 maybe located near the bottom of theshaft and driven by any suitable gearing. In this application IOO of myinvention I preferably construct a stationary floor just above thegearing for operating said Wheel L3-I.

It will be observed from the foregoing description that all suddenshocks and concussions are altogether avoided by the peculiar mountingof the suspending-Wheel upon the coil-springs. To further provideagainst any possible jar, I provide the coil-springs 3l, ivhich supportthe respective seats under independent Spring tension.

The construction and operation of my improved apparatus are Very simpleand cheap; but at the same time it effectually accomplishes the purposein view-i. e., to thoroughly absorb the concussion or vibrationincidental to the ruiming of the apparatus and forni a yielding cushionsupport for the respective riders.

In some instances it is desired to employ a cross-head 40, consisting offour rotating arms and provided at the point of intersection with asocket or cap il, whereby the cross-head may be fitted over and restupon the upper edge of the shaft. Connected to the outer ends of thearms are four ropes I2, which eX- tend to the ground, where they aresuitably anchored. rIhe arms of the cross-head are sufficiently long tohold the ropes clear of the opposite parts of the device. It may also bedesired in some instances to connect the seats by ropes or cablesextending from the bottom of one seat to the bottom of the next adjacentseat. IVhere the machine is constructed in large sizes, a pulley 4:3maybe secured to the shaft below the platform and turned by means of acable from some suitable motor.

These and other changes in the form7 proportion, and minor details ofconstruction maybe resorted to without departing from the principle orsacrificing any of the advantages ofthe invention.

Ilaving thus described my invention, what I claim as new, and desire tosecu re by Letters Iatent, is-

l. In a merry-go-round7 the combination with a power-shaft, of springsmounted thereon,and a seat-supporting wheel adapted to rotate with saidshaft but connected to said springs so as to be capable of verticalmovement on said shaft, substantially as described.

2. In a merry-go-round, the combina'ttion with asuitable power-shaft, ofcoil-springs mounted on the same, a supporting-Wheel also mounted onsaid shaft and connected to said springs, seats, and spring devicesforcenneeting said seats to the supporting-ivhecls, substantially asdescribed.

3. In a merry-go-round the combination with a suitable frame, of avertical shaft mounted on the same, coil-springs surrounding said shaft,a suspending-wheel also surrounding said shaft and lying between saidcoil-springs so as to be resisted against movement in either direction,and seats mounted on said suspen din g-Wheel,substantially as described.

In testimony whereof I have signed this specification in the presence oftwo subscribing Witnesses.

OLE R, IIAUSKEY.
